Re: Husqvarna 2100 performance upgrade?

If I machine the squish band for proper clearance, wouldn't the port timing be effected with the taller piston?

Would it increase performance?

Yes, it does alter the port timing and the exhaust and transfers would have to be raised up to get the performance you want.

Some people take a little rim cut on the deck of the taller pistons in the squish area and this minimizes the timing difference.

You could do a pop-up on the piston to make it clear which would leave the exhaust and transfer timing alone.  I'd personally still change them to get more performance though.  Here is a 2100 with a 395 piston I did.  It also has a 394 carb and a custom made v-stack.
